Abstract

Poststreptococcal glomerulonephritis (PSGN) is one of the most well-known and important infectious renal diseases resulting from a prior infection with group A β-hemolytic streptococcus. The typical clinical characteristics of the disease reflect acute onset with gross hematuria, edema, hypertension and moderate proteinuria after the antecedent streptococcal infection. In children, usually PSGN is healed spontaneously but if it combines with fast progressing glomerulonephritis, it would be developed to chronic renal failure. Therefore, it is important to make a fast diagnosis and treatment by simple tools to predict the course and the prognosis of disease. Sonography is a simple tool for diagnosis but there is no typical renal sonographic finding in PSGN, so it is difficult to predict the course and the prognosis of disease by sonographic findings. In comparison between two cases of renal sonographic findings in PSGN, a patient who showed more increased echogenicity in more extended area of renal sonography had the severe results of renal pathology, prolonged treatment period and low serum C3 level. Here, we report the different findings of renal sonography and pathology depending on the degree of severity between two patients. Thus, it is necessary to gather more information from further studies to make a consensus about the relationship between the renal sonography and the prognosis of disease in PSGN.
